In a programme for Channel 4, Beeny decided that she had found "lovely make-up and moisturisers which don't have any chemicals in them".

Green Goddess Julia Stephenson declared war on "electrosmog" in the Independent newspaper and Gwyneth Paltrow decided that a vegetarian diet was the way to prevent tumours.

The biggest concentration of celebs slapped on the wrists for pseudoscience were those who helped Nintendo to advertise Dr Kawashima's Brain Training, a game that requires players to complete puzzles in a bid to keep them mentally agile and lower their "brain age".
